The Athletics.app app supports multiple MacFinish instances at the same time.
Make sure you set the IP address correctly in both the Athletics.app app and in both MacFinish instances.
In the Athletics.app app, change the IP address to the IP address of the computer running Athletics.app. If you leave this on the default setting (127.0.0.1), Athletics.app can only be accessed from the local computer. In both MacFinish instances, you then set the IP address to be the same as the one you entered in the Athletics.app app. That way, all MacFinish instances on the same network can connect to the Athletics.app app.
